Hi Thomas - There should be one call to the drive() and it should be inside the try block. You have one that is above the try block. Also, in the catch block give the IllegalArgumentException some name, I used exp here. You also shouldn't have throw inside the catch block. Just print a warning for the user or use the getMessage() method to display the error message:

public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
        try {
          kart.drive(2);
        } catch (IllegalArgumentException exp) {
          System.out.println("Exception thrown!");  
          System.out.printf("The error was: %s\n", exp.getMessage());  
        }
    }
}
